Opioid analgesic use has increased dramatically in emergency departments (EDs), but the relative contribution of physician trainees has not been explored. We assessed trends in opioid utilization focusing on ED encounters where a physician trainee was involved. ⋯ Opioid utilization patterns for visits involving trainees reflect similar trends in attending practice, and highlights the more liberal opioid prescribing climate over time.

The Centers for Disease Control and Prevention (CDC) have published guidelines for opioid prescribing, with the goal of helping guide clinicians to make safe prescribing choices. In the form of 12 statements, the CDC offers guidance that at times is not supported by the evidence or introduces new concepts (such as a requirement that opioids improve function). Our objective was to examine the new guidelines in terms of how well they could strike the balance between keeping opioids accessible to those who need them while appropriately restricting their use. ⋯ The CDC guidelines offer some reasonable and laudable guidance, but they also make some recommendations which are not supported by current scientific evidence. We also noted that the urgent need for greater education among opioid prescribers was not addressed in the new guidelines.

Use of chronic opioid therapy has increased substantially over the past few years, even though opioid therapy is associated with potentially serious harms, including opioid-related adverse effects and outcomes. Prescription of opioids for chronic pain, particularly nonmalignant chronic pain, remains controversial. In the midst of this controversy, patterns of actual prescription and influences on these patterns are not well understood. This study aims to describe the frequency of prescription of opioid analgesics in a university hospital, the attitudes of doctors towards this category of drugs, and the follow-up modalities of patients taking these drugs. The study also explores the association between the practitioners' characteristics and the modalities of prescription. ⋯ The results of this study were compatible with those of other recent studies about opioid prescription. The doctors practicing in the university hospital Hôtel-Dieu de France de Beyrouth present comparable prescription patterns, independent of their personal or professional characteristics, and they are more confident in their prescription when professionally trained for it. However, they exhibit a notable heterogeneity in their attitudes towards opioids and in their modalities of evaluating patients receiving long-term treatment. These results suggest a need for additional training in the management of this category of drugs.

Delirium is a frequently occurring syndrome in patients admitted to the intensive care unit (ICU) or medium care unit (MCU), yet the pathophysiology remains poorly understood. An excess of central serotonin can lead to an altered mental status, associated with autonomic hyperactivity, and neuromuscular excitation. Drugs with serotonergic properties are frequently and for prolonged periods administered to ICU/MCU patients. Therefore, central serotonergic toxicity may constitute a predisposing, contributing or precipitating factor in the emergence of delirium. The purpose of the present study is to determine the number of patients admitted to the ICU or MCU who are diagnosed with delirium and who show characteristics of serotonin toxicity in association with the administration of serotonergic drugs. ⋯ A significant proportion of delirious patients in the ICU might in fact be classified as suffering from central serotonin toxicity. The awareness of potential serotonin toxicity is low among physicians.

Opioids are an important component of the drug treatment of patients with acute and chronic pain. They differ in effectiveness, side effect profile and the risk of interactions. In this article the pharmacokinetic mechanisms of drug-drug interactions at the level of biotransformation are described and the clinical consequences which can arise are discussed. The relation of the active components to the two isoenzymes CYP2D6 and CYP3A4 is of major importance for assessing the potential drug-drug interactions of opioid analgesics at the level of the cytochrome P450 enzyme.
